Here’s a new feedback today. He sent me his feedback after receiving Fidelizer Pro yesterday.

Everything worked smoothly. I used Purist, and can definitely tell a difference (good) over Extremist Free.

Thanks so much,

Jim

To make the most of sound quality improvement, upgrading to Pro version is definitely a good investment. 🙂

Here’s another feedback today. He used Fidelizer Pro on machine without internet connection at all for optimal result.

Hello again,

I’ve tried out Fidelizer Pro for only a couple of days and I’m stunned. What an improvement! It’s just like magic. The sound is more natural, detailed, bigger, firmer, airier. The list just goes on and on.

You really are in service for a better future for the recorded arts. Thank you!

Kind regards,
Vidar

Here’s a new feedback today. This time it’s from a customer who uses highend system.

Hello Keetakawee,
Improvements after installation of Your program are significant and more audible compare to AO 2.1!
Thank You, now I can barely recognize my favorite source ( APL HiFi) from PC, both connected with APL dac!

Greetings from Black Sea coast, Georgi!

APL is one of SACD sources I considered before in past. Glad to hear Fidelizer Pro works up pretty good with it. 🙂

Here’s another feedback today. This time is from Fidelizer Plus user who started to notice the improvement recently.

Hi Keetakawee,

Thank you. I have tried your free version few times in the past, right from the first versions when you released the program. I’ve never been able to hear clear difference made by it but yesterday evening when I auditioned once again, I just so much enjoyed the music I heard that I decided to try your plus version.

I also fully read the two threads in Head-Fi regarding your product, also the one in sound science forum where they grilled you about measurable differences. I’m senior Head-Fi’er myself and started my hobby with headphones. What I have learnt in 16 years in this hobby is that not every difference is measurable, especially in digital audio. My latest findings confirm that USB cables have clear audible differences and so do power cables, even though I was very skeptic about these two.

I use single PC Win10 setup with foobar2000 to TeddyPardo U2S USB bridge (throudh Chord SilverPlus USB cable and AQ JitterBug) to Naim DAC and forward to my Naim setup.

Greetings from Finland!

With enough time and experience, I’m certain audiophiles will notice in hard won improvement with Fidelizer. 🙂
